【摘要】 通过IR/TPD的改进方法,测定了氨在氢型丝光沸石(HM)上的Bronsted酸位上的脱附活化能和相应的集居数。结果表明,在HM上有三种不同强度的Bronsted酸位,分别对应脱附活化能为63.6、49.8和35.4kJ/mol。更多还原

【Abstract】 The activation-energies of desorption and population of Bronsted sites for ammoniaadsorbed on H-Mordenite have been measured by an advanced IR-TPD technique. Theresults show that there are three different Bronsted sites corresponding to three differentactivation-energies of desorption, 63.6, 49.8, 35.4 kJ/mol and three different population,0.35, 0.19, 0.10.更多还原
